Strength and Determination

Founded in 2000, our namesake is the most westerly island of the Inner Hebrides of Scotland, acknowledging the roots of our company founder. And while the Isle of Tiree may be somewhat small, it is also ruggedly spectacular and stands firm against the winds and waves of the North Atlantic. Strong and determined. Just like us.

We are an accomplished and diverse team of more than three hundred uniquely talented individuals. We are innovators, problem‑solvers, and best‑in‑class real property and project management professionals focused on leveraging our collective capabilities to solve defining challenges for our clients.

Canada’s National Capital Region is our home, but our work takes us around the globe. Our success is built on a strong foundation that is instilled with a genuine passion for the projects we undertake and their positive impact on shaping our shared environment – getting to work on such projects is an inimitable privilege we don’t take for granted.

We are proud of our Tiree Team, and our focus remains on continuing to create opportunity and empowering individuals to flourish, grow, and celebrate success. People come to us to work on our engaging, iconic, and complex programs and projects. They come to collaborate, create, and contribute. They come to be heard, respected, and formulate long-lasting relationships and connections with their colleagues. They come to learn from industry experts and advance their careers. And…they come strong and determined.
